With online mattress stores becoming more and more popular it is growing more and more difficult to find the perfect mattress for your needs. With options for innerspring, foam, memory foam, and more it can be hard to choose one in person, let alone online.
This article will examine two of the most popular brands head to head. In this Leesa vs. Casper mattress showdown, we will look at all the details of each mattress and compare them side by side in order to help you make a well-informed decision.
Most retailers will show you comparisons of the different mattress from the same company. Here, we will show you side-by-side how the competition rates against each other.
$525 - $1100
8 – 12 years
The Leesa mattress has a larger comfort layer but it is wrapped in a transition layer. This allows for a more firm feeling without sinking in. Side and front sleepers will get the most benefit here.
$550 - $1150
8 – 12 years
The Casper mattress uses a four-and-a-half-inch comfort layer that allows for a firmer feel while still being able to sink in to the bed. The above average quality and customer service make this a good choice for most side and back sleepers.
Firmness and Support
Both the Leesa and the Casper are in the firm end of the scale. With thick support foam topped with layers of memory foam and comfort foams, the choice can be a difficult one to make. If they have the same level of firmness, how do you choose?
The only difference is in the support. Leesa mattress firmness comes from the six inches of support foam and two inches each of Avena foam and memory foam. This gives a more solid feel to the mattress with a slight bounce.
When you lay on it though, you tend to sink in only a little bit. This is great for side and font, or stomach, sleepers as you get the support you need with enough comfort for your position. The slight hug from the foam is nice as well.
The Casper mattress, on the other hand, has a five-inch base foam and that is topped with an inch and a half of memory foam sandwiched between two inch and a half layers of poly foam. This results in a firm mattress with a little more sinking.
When you lay on the Casper, you will have more of an in the mattress feel instead of on the top of the mattress feel. This is better for back sleepers as well as side sleepers.
Winner: This is a tie, depending on how you sleep most often, the firmness and support are near equal.
Couples will find that some mattresses provide better motion transfer than others. If your partner (or you) moves a lot while sleeping, or gets up and out of bed earlier, motion transfer can be a pretty big deal.
You want a mattress that will not move on one side just because there is movement on the other. The Leesa has very subtle, if any, motion transfer. You will most likely not notice when your sleeping partner gets out of the bed or turns over in the night.
The Casper also has great motion isolation. The movements are hardly noticeable and getting in, or out of, the bed on one side will not disturb the person sleeping on the other.
Winner: Another tie. The motion isolation is near identical in both models.
Construction and Materials
What the mattresses are made from is also important. What works for one may not work for another.
The Leesa has high-quality foam inside the cover. The Support foam is six inches thick while the Avena (or eggshell) foam on the top layer sits at an inch and a half with memory foam in the middle.
The cover is a single cut polyester and lycra material with only one seam in the corner. While the look isn’t important as it will be covered with linens, Leesa has a modern and bold design with a gray and white “four bar” design.
The Casper also has high-quality foam with a 5-inch support base foam and 3 inches of poly foam wrapped around the memory foam layer.
The cover is a more traditional look with a two-tone coloring of white top with grey sides. The cover is 100 percent polyester and is porous and very breathable.
The overall construction of both mattresses is high quality with attention to detail. As soon as they are unboxed, they are ready to use.
Winner: The Leesa takes a slight edge here. Both being breathable, the Leesa is slightly sturdier when it comes to moving and turning.
Off-Gassing and Smell
Any boxed mattress will need time to expand and reach it’s full size, during this process, there will be a distinct smell and some slight off-gassing. The major concern is with the materials being used and how they are manufactured.
All foam and adhesives will have some levels of VOC gases. Being wrapped in plastic and boxed up will allow these gases to accumulate. Every mattress should be opened and allowed to air out for several hours.
Some find that allowing the mattress to air out outside is best. The initial odors can be quite strong. The general rule of thumb is to allow at least 8 hours for the mattress to expand and breathe.
Some people with breathing conditions or high sensitivities may require a longer airing out period. People living with Asthma, for example, may find that they need to let the mattresses air out in a well-ventilated area with a cross breeze for a few days. This is a personal decision and should be something to consider before making a purchase.
The Leesa has minimal odors and off-gassing which generally dissipate within a few hours. Very few people actually reported the odors as disturbing or bad. For the expansion and off-gassing, you should allow the Leesa to rest for at least 8 hours before laying or sitting on it.
Leesa also takes their care of VOCs and off-gassing to the next level by ensuring that each mattress is Eco-friendly and certified by Certi-PUR-US.
The Casper needs a little longer for the off-gassing odors to dissipate, but not much. Reports are that most of the odors are gone within the first ten hours. Depending on how sensitive you are to the VOCs, you may need to add extra time for airing out. This goes for both models, not just the Casper.
The Casper, like the Leesa, is also Certi-PUR-US certified on every layer of foam and ensures that the flame retardant materials are Eco-friendly and free of heavy metals.
Winner: This is a tie. The amount of off-gassing and airing out time will depend greatly on your personal level of sensitivity.
Who Should Buy A Leesa?
The Leesa mattress is designed to work for almost everyone. If you are looking for a firm mattress that will give you a sink-in hugging feeling that supports back and side sleepers, the Leesa may be the right choice for you.
With Certi-PUR-Us certifications, you can rest assured that VOCs and other toxins are low or non-existent. From opening the package to your first sleep is only about eight hours. Some with higher sensitivities to the off-gassing, though, may need to wait a few extra hours.
Leesa offers great customer service and construction quality that makes the mattress easy to use, move, and sleep on. It is breathable and comfortable with a great warranty. The only issue with the Leesa will be those that like to sleep on their stomach, as the extra give may prevent a restful sleep. To get more information on Leesa mattresses, check out our review.
Who Should Buy A Casper?
Casper makes a high-quality mattress as well. The firm mattress adds support for those looking for a more “on the top” sleeping feeling. There is a give in the foam, but it is less than with the Leesa. This might be a better option for stomach or front and side sleepers.
If you toss and turn, or if your partner does, Casper’s low motion isolation means you won’t be disturbed when your partner gets out of bed. The Casper is also certified and has low-level VOCs that quickly become non-existent.
The quality of the build is only limited in the cover design. The polyester cover can tear if the mattress is moved often or without care. Once set up and in place, though, this worry is diminished. If you'd like to get more info on Casper, read our review.
